510	DAV module COPY & MOVE can't handle regex destination URI	Qiang Yu		"I configure NGINX to be a WebDAV server:
{{{
server {
listen 8283;
server_name 127.0.0.1;

root /home;

charset utf-8;
create_full_put_path on;

dav_methods PUT DELETE MKCOL COPY MOVE;
dav_ext_methods PROPFIND OPTIONS;
dav_access user:rw group:rw all:r;

location / {
deny all;
}

location ~ ^/users/(\w+)(/.*)?$ {
alias /home/$1$2;
auth_basic ""emNAS"";
auth_basic_user_file /opt/emnas/etc/webdav/$1.ht;
autoindex on;
}
}
}}}

I tested COPY and MOVE not work. Track the code with GDB, the problem
is in function ngx_http_dav_copy_move_handler() which calls ngx_http_map_uri_to_path()
to map destination URI to destination path. But it map destination URI to source path.
So the MOVE does nothing, the COPY report file exists error.

For example,
MOVE http://localhost:8283/users/admin/aaa to http://localhost:8283/users/admin/bbb
results an FS op
RENAME /home/admin/aaa to /home/admin/aaa
which does nothing.

The wrong path from correct URI is generated by ngx_http_script_run().
ngx_http_dav_copy_move_handler() calls ngx_http_map_uri_to_path() first time
to convert source URI to source file path, then second time for destination URI.
It seems the previous regex capture result is not regenerated in the second run
of ngx_http_map_uri_to_path() within the same HTPP request.
